We know the Gracies at least trained SAMBO and wrestling before UFC. As well as trained Judo. They borrowed techniques from these arts to add to their repitore. Is it fair to call it PURE BJJ when so much is borrowed?

Hapkido? didnt know he trained in that, i've only seen a few highlight clips of the match so i don't really know how it went. How did gracie use hapkido tho? It's funny if he did seeing as alot of people think aikido, hapkido are a waste of time.
